LINE-GATE FOR CONCRETE-CHUTES.

memos.

Application filed December 12, 1913.

To all whom it may concern:

Be it known that I, WILLIAM H. INsLEY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Line-Gate for Concrete-Chutes, of whichthe following is a specification.

The object of my invention is to produce an improvement in pouringchutes commonly used in the erection of reinforced concrete buildingsfor delivering the fresh concrete mixture to desired points, theinvention being particularly directed to that portion of the apparatusby which the stream may be deflected from a main trunk line into shortlaterals.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation of a fragment of a trunk line chuteequipped with my improvement; Fig. 2 a plan; Fig. 3 a section on line 33of Fig. 1; and Fig. 4 an elevation of a fragment of the trunk line chutewith the valve omitted.

In the drawings, 10 indicates the main trunk line chute of ordinary typebraced at sufiiciently separated points by the binding straps 11, 11.Between the binders 11' the under side of the chute 10 is cut away inthe manner illustrated in Fig. 4, the upper or initial end being firstcut inwardly substantially square, as indicated at 12, thenlongitudinally, as indicated at 13, then upwardly and forwardly, asindicated at 14:, and then forwardly and downwardly as indicated at 15.Adjacent the part 15, at each side, the chute 10 is provided with adownwardly extending ear 16 which extends over the cut away portion andis provided with an opening for the reception of a pivot bolt 17. Thetwo pivot bolts carry the opposite sides of a trough-shaped valve 18adapted to fit in the opening 121314:15 in the manner clearlyillustrated in Fig. 1, the lower forward end of the trough lying insideof the trunk line chute while the upper rear end of the valve liesoutside of the trunk line chute, this arrangement being permitted by theformation of a notch 19 in the upper edge of each side of the trough andthe slight outward displacement of the edge of the valve to the rear ofthe notch and a slight inward displacement of each edge of the troughforward of the notch so Specification of Letters Patent. Patented Jan,19 1915 Serial No. 808,200.

that that portion of the wall of the trunk line chute at the cornerbetween the parts 1-1 and 15, will lie in the notch 19.

Secured rigidly to one side of the valve 18 is an operating arm 20 whichis also conveniently pivoted upon one of the pivot bolts 17 and extendedfrom thence forwardly and downwardly for the reception of a pull rope21. The upper rearward end of the valve 18 is provided with astrengthening binding strip 22 which at its ends is turned outwardly toform fingers 23 beneath which the hooked ends of catches 24: may pass.The catches 24: are conveniently formed at the ends of a yoke orU-shaped bar 25, the central portion of which bridges the main chute 10and is pivotally supported in inverted U-shaped brackets 26 pivoted orotherwise suitably secured to the upper edges of the chute 10.

The hooks 24. are normally urged to valve retaining position by asuitable spring 27.

Suspended from the chute 10 by Suspender straps or yokes 28, 28 is ahopper 29 suitably notched at its front and rear edges, as indicated at30, to straddle'the under side of the chute 10 above and below the valve18. Mounted upon the hopper 29 is a sheave 31 which serves as a guidefor a pull rope 32 attached to the yoke 25.

Under normal conditions the position of the parts is that shown in Fig.2, so that material, flowing through chute 10, will flow over gate 18without interruption or leakage. When flow is to be established to thehopper 29 the operative pulls upon rope 32 thus withdrawing latches 24and permitting the front end of gate 18 to drop around pins 17. Whenflow past hopper 29 is to be reestablished the operative pulls upon rope21 until the gate is restored to the position shown in Fig. 1.

It will be seen that ropes 21 and 32 are entirely protected from theflowing material and it will be understood, of course, that these ropesare extended to any desired point.

I claim as my invention:

1. The combination, with a delivery chute having an opening in itsbottom, the upper edges of said opening being shouldered, as at 14, atrough-shaped gate lying outside the chute at its upper end and insidethe chute at its lower end and having notches in its edges receiving theedges of the chute opening, a pivotal support for said gate, anoperating arm for the gate, and a latch for holding the gate in closingposition.

2. The combination, With a delivery chute having an opening in itsbottom, the upper edges of said opening'heing shouldered, as at 1%, atrough-shaped gate lying outside the chute at its upper end and insidethe chute at its lower end, a pivotal support for said gate, anoperating arm for the gate, and a latch for holding the gate in closingposition.

In Witness whereof, L have hereunto set my hand at Indianapolis,Indiana, this 28th 15 day of November, A. I). one thousand nine hundredand thirteen.
